How it works
Each quarter's payout is the deposit times the annual rate, divided by four. The principal is untouched throughout and returned in full at the end of the term, so the income is identical every quarter for five years.
The figure worth attention is the last one. The same rate compounded quarterly rather than paid out would produce a materially larger total, and the gap is shown explicitly. It is not an argument against the scheme — someone who needs the income needs the income — but it is the real cost of the choice.
More detail
The rate is fixed when you deposit and holds for the whole term, which is a genuine advantage over a bank deposit whose rate is reset on renewal. It also means the income does not rise with inflation over five years.
The ₹30 lakh ceiling is per person rather than per household, so a couple who both qualify can hold ₹60 lakh between two accounts and roughly double the income.
